Chapter 5 Eukaryotic Cells and Microorganisms

Fungi produce which structures for reproduction and multiplication?

Spores

Saprobes (saprophytes)

obtain energy from dead, decaying matter => decomposers.

asexual spores

produced by the mitotic division of a single parent cell

Cilia are similar in structure to flagella and are commonly found on which microbial cells?

protozoans

In a helminth life cycle, which host harbors the adult, secuallyactive stage of the pathogen?

definitive host

The Golgi apparatus

A system of membranes that modifies and packages proteins for export by the cell

Nucleolus

Found inside the nucleus and produces ribosomes (site of ribosomal RNA synthesis and ribosomal subunit assembly)

Which of these organisms has the best potential to survive in extreme environments?

Fungi

Heterotroph

Acquisition of nutrients from organic materials (subtrates)

parasite

An organism that feeds on a living host

True or False: All microbes that are unicellular, photosynthetic, and motile are classified as protozoans.

False

What is a major difference between bacterial and eukaryotic ribosomes?

Bacterial and eukaryotic ribosomes differ in size. The eukaryotic ribosome is the larger 80S variety (combo of 60S and 40S subunits)

True or False: Archael and bacterial cells use chloroplasts for the process of photosynthesis.

False

What mitochondrial structures are the site of the enzymes and carriers used to make ATP in the electron transport system?

Cristae

nuclear envelope

Double membrane perforated with pores that control the flow of materials in and out of the nucleus.

Which cytoskeletal fibers attach to and move chromosomes during mitosis?

Microtubules

Which term most accurately describes a fungus growing on live human skin?

Parasite

Chloroplasts are the site of what process in eukaryotic cells?

Photosynthesis

Which of these groups causes the most casualties on an annual basis globally?

Protozoa

Role of mitochondria

Provide cell with energy through cell respiration

Amoeba utilize what structures for motility?

Pseudopods

sexual spores

These are produced by the union of genetic material from two different strains

Chromosomes

Threadlike structures made of DNA molecules that contain the genes
